Elimination of glowing artifact in digital images captured by an image sensor |
摘要 |
A source/drain region of a transistor or amplifier is formed in a substrate layer and is connected to a voltage source. A glow blocking structure is formed at least partially around the source/drain region and is disposed between the source/drain region and an imaging array of an image sensor. A trench is formed in the substrate layer adjacent to and at least partially around the source/drain region. The glow blocking structure includes an opaque material formed in the trench and one or more layers of light absorbing material overlying the source/drain region and the opaque material.
